This is a very special episode of "The Skyentists", where astronomers Kirsten Banks and Ángel López-Sánchez answer many "spooky" astro-questions, including what is the scariest thing in the Universe. Of course, this is an excuse to talk about Halloween and the origins of this festivity that, yep, it is very related to Astronomy. Plenty of feedback (and auto-feedback) is also answered in this episode. In "Space News" we talk about the new citizen science project "The Hunt of Galaxy Clusters" and how neutron stars are related to different kind of pasta. For our "What's Up" segment we talk about the giant star-forming region 30 Doradus, also known as the "Tarantula Nebula". We also mention some few other astronomical objects with a Halloweeny theme. We wrap up the episode with some thoughts about losing the dark and a nice surprise!
